（1）如下图先创建一个普通的maven项目。项目名为 eurekaServer （随意起名）

（2）pom 增加以下依赖

<?xml version="1.0" encoding="UTF-8"?>
    <project xmlns="http://maven.apache.org/POM/4.0.0"
             xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
             xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
        <modelVersion>4.0.0</modelVersion>
    
        <groupId>com.zhihao</groupId>
        <artifactId>eurekaServer</artifactId>
        <version>1.0-SNAPSHOT</version>
    
        <name>eurekaserver</name>
    
        <properties>
            <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
            <maven.compiler.source>1.8</maven.compiler.source>
            <maven.compiler.target>1.8</maven.compiler.target>
        </properties>
    
        <parent>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-parent</artifactId>
            <version>2.0.0.RELEASE</version>
        </parent>
    
        <dependencyManagement>
            <dependencies>
                <dependency>

                    <version>Finchley.BUILD-SNAPSHOT</version>
                    <type>pom</type>
                    <scope>import</scope>
                </dependency>

                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-starter-netflix-eureka-server</artifactId>
            </dependency>
    
            <dependency>

                <artifactId>junit</artifactId>
                <version>4.11</version>
                <scope>test</scope>
            </dependency>
    
        </dependencies>
    
        <repositories>
            <repository>
                <id>spring-snapshots</id>
                <name>Spring Snapshots</name>
                <url>https://repo.spring.io/libs-snapshot</url>
                <snapshots>
                    <enabled>true</enabled>
                </snapshots>
            </repository>
        </repositories>
    
        <build>
            <finalName>eurekaserver</finalName>
        </build>
    
    </project>

（3）在src/main/java 下创建启动类:

package zhihao;
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;
    @EnableEurekaServer
    @SpringBootApplication
    public class App {
    
        public static void main(String[] args) {
            SpringApplication.run(App.class, args);
        }
    }

（4）在src/main/resources 下创建配置文件（如果没有目录，可以手动创建），文件名application.yml ，用property也可以。

server:
      port: 8800
    
    spring:
      application:
        name: EurekaServer
    
    eureka:
      client:
        registerWithEureka: false
        fetchRegistry: false
        serviceUrl:
          defaultZone: http://localhost:${server.port}/eureka/

（5）运行启动类，访问[http://localhost:8800/][http_localhost_8800] ，看到注册中心首页如下，表示成功了。
